Technical Information
Dimmer
LV dimmers, for electronic transformers, 60 to 800 W,60 to 800 VA, for two-way switching (5TC8258)
Technical specifications
Schematics
Power supply Mains connection 230 V (2-wire method), rated voltage: 230 V AC, 50 Hz
Protection against short-circuits
Reversible operating electronic fuse
Protection against overloads
With additional temperature cutout, which shuts down the dimmer in the event of an overload and only
resupplies it automatically with power when the overload is eliminated after the device has sufficiently
cooled down
Load output
• Number Two terminals for two-way switching ( and )
• Rated voltage 230 V AC, 50 Hz
• Rated load (up to 35 °C ambient temperature)
- Incandescent lamps 60 ... 800 W
- HV halogen lamps 60 ... 800 W
- LV halogen lamps with electronic transformer 60 ... 800 VA
- Note Does not support connection of:
• Energy-saving lamps
• Magnetic transformers
- Maximum connected load at ambient temperature
Warning: The connected load must be reduced
by 25 %, depending on operating conditions
• For mounting on wood, Rigips, gas concrete or
cavity walls
• For installation in multiple combinations or
surface-mounting enclosures
If using highly thermally insulating materials
(e.g. glass wool), it may be necessary to reduce
the connected load even further
Terminals
4 screw terminals with anti-slip terminal body, the following conductor/cross-sections are permissible:
• 0,5 ... 4.0 mm² solid
• 0,5 ... 2.5 mm² finely stranded, with or without end sleeve (without insulating collar, gas-tight crimp
connection)
Mechanical specifications

• Degree of protection (acc. to EN 60529) IP20
• Overvoltage category (acc. to IEC 60664-1) III
• Standard According to EN 60669-2-1
EMC requirements According to EN 60669-2-1, EN 61000-6-3 and EN 61000-6-1
Environmental specifications
• Ambient operating temperature –5 ... +45 °C
• Storage temperature –25 ... +70 °C
